MEANS FOR PROTECTING SAFES.

SPECIFIGATION forming part of Letters PatentNo. 720,330, dated February 10,1903.

Application filed February 7,1902. Serial No. 92,984. on ml del.) I e To all whom it may concern:

Be it known that I, GEORGE W. CRAIG, a citizen of the United States, residing at Lyons, in the county of Ionia and State of Michigan, have invented certain new and useful Im provements in Means for Protecting Safes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. v

. This invention relates to means for protecting safes, vaults, &c., from unauthorized attempts to open them or otherwise tampering with them; and the object of the invention is to provide means which under certain conditions will vitiate the air around the safe or vault to such an extent as to render the vi-' cinity of the safe or vault dangerous for a tion; but it is to' be understood that my invention is not restricted to the specific devices illustrated and described nor to the par ticular fume-generating composition men tioned. 1

In connection with the specification.refer-' ence must be had to theaccompanying' drawings, in which Figure 1 is a side elevation of a safe and a I preferred form of my protective devices, partly in section and in normal position. Fig.2 is a front elevation with the screen partly broken away to show the front of the safe. Fig; 3, is a top-plan view of the devices for supporting and breaking the frangible vessel, and Figs. 4 and 5 are respectively side and, end, viewsofFig. 3.

A indicates the safe to be protected, and B is a'mova'ble object, such as a screen, in close proximity to the front of the safe and which must be moved before the door of the safe can be opened.

0 represents acord or'wire adapted to be detachably connected to the bottom of the soreen, so as to be moved when the screen is moved. 7

'1) represents an uncovered box adapted to contain the frangible vessel and the device forbreaking it, and in the case of a safe this box will preferably be placed under the safe.

E represents a block or base upon which" the fra'ngible vessel m is supported. This vessel may conveniently be in the form of a glass vial fitting in a loop or pocket formed in a strap Z, secured to the base.

astriker or jaw f, pivoted to the base and adapted to be impelled by a coil-spring z to strike the vial with sufficient force to break 1 the latter. In order to..-detachably lock the striker f under tension of the spring, I provide abarj, which is pivotedto the base and extends over the striker fwhen the latteris folded down on the base'under the tension of the spring, and the free endof the bar is adapted to be engaged bya trigger It, which is pivoted on the base, and when so engaged the bar j will hold .the striker under the tension of the spring. The cord onwire C is connected to the trigger, and it isobvious that when the screen B is moved it will move the cord 0 and cause the latter to exert a pull on the trigger and release the latter from engagement with the barj, and the striker f will then under the influence of the spring 4; be caused to strike the vial m and break the latter.

A preferable fume-generating composition to befcontained in the vial is'as follows:

camph'or-gum, one part; ammonia, two parts; oil of mustard, four parts; kerosene-oil, eight parts, and chloroform two parts. Any other suitable composition may, however, be used.

-The b'ox D is not essential, as obviously the ICC ing a fume-generating composition, a movable body adjacent to the object to be protected, and means actuated by the movable body for breaking said vessel, substantially as set forth.

2. In a protective means for safes, &c., the combination of a frangible vessel containing a fume-generating composition, a movable striker supported to break the vessel, a move able body adjacent to the object to be protected, means for impelling the striker, de-

vices for detachably looking the impelling means against action, and a connection be-,

tween the movable body and the locking devices, substantially as set forth.

In testimony whereof I aifix my signature in presence of two witnesses.

GEORGE W. CRAIG.
